    Steel Making ProcessThe process of making steel by removing the impurities from hot metal. Hot metal produced from a blast furnace is high in carbon and contains impurities such as phosphorous and sulfur. To prevent red shortness however it is necessary to remove sulfur from this hot metal through the KR (Kanvara Reactor).
